摘　　要：随着仪器采集精度的提高,分析、反演解释技术的长足进步以及油气藏重力勘探的需要,出现了重力归一化总梯度法。结合测井资料,通过重力模型正反演计算,得出高精度重力勘探浅层油气藏是可行的结论。重力归一化总梯度法自提出以来获得了不断的完善发展,并在某气田的实践中被证明是勘探浅层油气藏的有效方法。With improvement of the instrument data acquisition accuracy,considerable progress of the analysis.inversion interpretation technology and the need for gravity exploration of oil and gas reservoirs, the normalized full gradient method of gravity anomaly appears. Combined with logging data, the conclusion is made that it is feasible to conduct high-precision gravity exploration of shallow oil or gas reservoirs through the gravity modeling and inverse calculations. The normalized full gradient method has been perfacted and in the exploring of a shallow oil or gas reservoirs it has proved an effective exploration method.
